This document is an assignment for Keiser University’s NUR 4108: Public Policy and Risk Management in Nursing course, specifically focused on Chapter Nine – Sample Size. It requires students to critically appraise the sample sizes used in two quantitative studies.
This assignment is intended for nursing students learning to evaluate research methodologies. It’s used to apply concepts of sample size adequacy and representativeness, skills essential for evidence-based practice. It exists as a practical exercise to reinforce understanding of research critique.
This assignment does *not* provide instruction on how to conduct a power analysis or determine appropriate sample sizes; it expects students to *apply* existing knowledge to evaluate published research. It also doesn’t offer complete answers or solutions.
The full assignment includes instructions to locate and evaluate two quantitative studies using provided critical appraisal guidelines (found on pages 247 and 253 of the course materials). It provides two example articles – “Digital Inequality During a Pandemic” by van Deursen (2020) and “Telemedicine in the COVID-19 Era” by Nittari et al. (2022) – along with specific questions to guide the evaluation of each study’s sampling method, size, and representativeness. This preview does not include the complete critical appraisal guidelines or answers to the questions.
